Hash_sha256

用于实现文本串的加密解密功能，程序自带密匙(Text string used to implement the encryption and decryption functions, comes with key program)

RSA数字签名的源代码 vc++6.0实现的版本(RSA Digital Signature vc source code version 6.0)

仿射 suanfa daima 加密 解密(affine suanfa daima affine )

IBE基于身份的加密系统的系统叁数程序，使用VC6.0开发(IBE identity-based encryption system of systems Triple the number of procedures, the use of VC6.0 Development)

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)

AES128bit加密算法。在PDF文档中有详细算法描述(AES128bit encryption algorithm. PDF documents are detailed in the algorithm description)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

说明：  用C++实现的图像加密和解密算法代码,功能强大(Using C++ implementation of image encryption and decryption algorithm code, powerful)

一个袖珍的vc++加密软件，同时还可以解密，加密文件的范围挺大的，几乎所有文件都可以加密，输入密码并解密，好像不是真正意义的加密，只不过是用文件额外加密的方法进行加密，较早时候的程序，不过编译还是顺利的。 (A pocket-sized vc++ encryption software, but also can decrypt encrypted files the scope of getting bigger, almost all the files can be encrypted, enter the password and decrypt the encryption does not seem real, but the file is an additional method of encryption to encrypt Earlier procedures, but the compiler is still smooth.)
